Column Width Not Working

Recently, I tried to define the width of a column as such:

{section}
{column:width=400px}
Cell 1A
{column}
{column:width=400px}
Cell 1B
{column}
{section}

However, Confluence would not recognize the defined widths. After spending hours trying to figure out the solution, I found a JIRA ticket that provided a workaround—add a blank column at the end of each section.

{section}
{column:width=400px}
Cell 1A
{column}
{column:width=400px}
Cell 1B
{column}
{column} {column}
{section}

Thanks to Tomi Strugar for the workaround.
